1,847,593 3/1932 Cameron l24/24 R 7 Claims, 5 Drawing Figures llll umuu ARCHERY BOW WITH VERTICALLY ADJUSTABLE SIGHTING DEVICE BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to improvements in sight assemblies for archery bows of the type disclosed in US. Pat. No. 3,120,222. The objects of this invention are to provide a new and improved simplified low cost sight assembly integrally mounted on a bow handle in a new and improved manner. The objects are attained by providing a guideway in the bow handle in the form of opposite pairs of intersecting inclined recessed guide surfaces centrally connected by an elongated slot and by providing an adjustable sight assembly in the form of a sight pin mounted on and carried by a pair of guide shoes mounted on the recessed guide surfaces in recessed relationship to the adjoining surfaces of the handle.

BRIEF DESCRIPTION OF THE DRAWING FIG. I is a side elevational view of an archery bow incorporating the invention;

FIG. 2 is another side elevational view of the archery bow of FIG. 1;

FIG. 3 is an enlarged partial side elevational view of the handle portion of the archery bow of FIGS. 1 and 2;

FIG. 4 is an enlarged cross sectional view taken along line 44 of FIG. 3; and,

FIG. 5 is another enlarged cross sectional view taken along line 5-5 of FIG. 3.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIGS. 1 and 2, a reverse curve takedown'type archery bow is shown to comprise a handle member 12, a pair of removable limb members 14, I6, and a bowstring 18. The handle member is of one piece cast metallic material having a gripping portion 20, an arrow rest portion 22, and a recessed window area portion 23 defined by relatively closely spaced generally parallel handle surfaces 24, 25, in which a sight assembly 26 is adjustably slidably mounted in an elongated sight mounting guideway 28 integrally formed in the window portion to extend longitudinally relative to the window area.

Referring now to FIGS. 3-5, the guideway 28 comprises a guide slot having first and second elongated guide shoe slot portions 29, 30 opening outwardly in surfaces 24, 25, respectively, each defined by longitudinal outwardly inclined guide shoe surfaces in the form of pairs of oppositely facing inclined recessed surfaces 32, 34 and 36, 38 centrally formed in the window portion 24 and extending transversely relative to the arrow rest portion 22. The pairs of surfaces 32, 34 and 36, 38 define first and second elongated guide shoe slot portions which intersect centrally of the window portion 24 to define an elongated rectangular connecting slot 40.

The sight assembly 26 comprises guide shoe means in the form of a plastic front first guide shoe member 50 slidably supported on guideway surfaces 32, 34, next adjacent the window opening surface 25, and a metallic rear second guide shoe member 52 slidably supported on guideway surfaces 36, 38. Each guide shoe has spaced generally parallel front and rear fiat surfaces 54, 56 of generally square peripheral configuration, a pair of opposite flat inclined support surfaces 58, 60 cooperable with the guideway surfaces, a pair of opposite flat straight surfaces 62, 64, and aligned central annular openings through which connecting and clamping means, in the form of a pin member 66, extends across the guideway through slot 40.

The size of the shoes is such as to locate them in the guideway in recessed relationship to the adjoining handle surfaces 24, 25. A plastic spacer sleeve member 68 surrounds the central portion of the pin and extends axially through slot 40 between the guide shoes 50, 52. The rear end of the pin is provided with an annular head 70 seated on a correspondingly shaped counterbore in shoe 52. The intermediate portion of the pin is threaded and loosely received within the sleeve 68 as well as within the aligned central opening in guide shoe 50. The connecting and clamping means further comprises a knurled locking nut member 72 threadably mounted on the threaded portion of pin 66 and abuttingly engaging the front surface of shoe 50 to tighten and lock the sight assembly in any selected adjusted position. The plastic material of shoe 50 is such as to enable some resilient compression. under load of the wedging force exerted by the nut member to facilitate the clamping action. A sight means in the form of a sighting knob 74 on the end of pin 66 is located in general alignment with the bowstring 18. Thus, the sight assembly may be adjusted to any selected position by loosening nut 72, sliding the shoes 50, 52 along the guideway surfaces 32, 34 and 36, 38, and tightening the nut at the selected position to resiliently frictionally retainingly engage the shoe surfaces 58, 60 with the guideway surfaces.
